Reply to Comment by Peace et al. on “Revealing the Cape Verde Hotspot Track Across the Great Lakes”

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract In Tao et al. (2025, https://doi.org/10.1029/2024GL110777), we presented a high‐resolution seismic anisotropy model, proposing that the Cape Verde (CV) hotspot caused enhanced radial anisotropy in the North American lithosphere. We also suggested that this interaction could have created zones of low‐lying topography that set the stage for ...

Congruent Weathering of Continental Silicates During Warm Periods: Evidence From Lithium Isotopes in Marine Sediments

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Dissolution of secondary clay minerals during continental weathering (hereafter clay dissolution) has been proposed as a mechanism to explain some of the low seawater lithium isotopic ratios (δ7Li) observed in the geologic past. However, direct evidence for clay dissolution on Earth surface remains limited, and the controlling factors are ...

Tracing Mantle Sources to Tectono–Magmatic Settings: Machine Learning Classification of Basalts Over the Past 1 Billion Years

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract The geochemical heterogeneity of the mantle, recorded by mantle‐derived basalts, offers crucial insights into the evolution of mantle sources. However, recognizing mantle end‐members of basalts is challenging, as traditional trace element proxies yield ambiguous overlapping results in older basalts.
